After I have tried some disk cleaner for use in the hand or at the bar, I came across the Floaty. It runs easily on the disk, without hacking, as at other times already is the case. Since I have several 450 l basin with curved tempered front glass covered most magnetic cleaner easily into the water if you go a bit too fast on the disc. This is not the case here, I can only recommend highly popular aquarium with curved lenses on the pelvis. With a height of 60 cm, there is often wet finger with the rod cleaners, even if I avoid any unnecessary contact, the fish sake. Price is acceptable, just good has its price. Cleans also quite good and with regular use "green washers" of the past were allowed to belong.
